>My guess exercise is beneficial only to some level, after that it has a big toll on everything. Including IQ, mental and general health, and so on.

What reason do you have for thinking this? As far as I’ve read, there’s no indication that athletes perform worse than the population average on any of these metrics.

Athletes outperformed non-athletes on standardized tests in a 2014 study of Texas high schoolers.[1] Professional soccer players/footballers outperform the population average on a variety of cognitive assessments.[2] Sub-4 minute mile runners have better longevity and lower risk of cardiovascular disease than average.[3] With the exception of contact sports like American Football which involve serious risks of injury, I can’t think of any example of elite athletes that are worse off on quality of life metrics than average people.
